Description
TECHNICAL FIELD
The present disclosure relates to a production management device of
a board production line that produces boards on which components
are mounted.
BACKGROUND ART
As disclosed in PTL 1, a board production line is configured of a
board production device, an inspection device and the like. Board
production devices perform various types of production processing
with respect to a board, and include solder printing machines,
component mounters, reflow machines, and the like. Inspection
devices inspect boards produced by the board production device, and
include solder inspection devices, optical inspection devices,
functional testers, and the like. With respect to boards produced
by the board production line, appropriate inspection is performed
by the inspection devices. For example, with respect to the board
which is at the final step of a production process, whether the
board functions correctly is tested by the functional tester (refer
to PTL 2).
In addition, in the board production line, in a case where a job is
switched according to a production plan, before performing a main
production process of mass-producing the boards, there is a case
where a test production process of producing initial boards is
performed. In the test production process, a given quantity of
initial boards is produced, and various types of inspection set in
advance are performed. There are cases where initial boards are
produced as dedicated boards used only for the inspection, and
there are cases where initial boards are produced as a portion of
production boards while also being used for inspection. By
inspection in the test production process, it is determined whether
the component types, control program, and parameters set at the
board production line are appropriate. The board production line
adjusts the board production device and the like based on the
determination result.

SUMMARY
Here, board production devices that configure the board production
line can receive an operation command by an operator in the middle
of performing the test production process. Therefore, there is a
concern that the main production process will be mistakenly started
before determining the quality of the initial board by the test
production process if this occurs, in a case where it is determined
that the initial board is defective by the test production process
later, the boards produced to that point become useless, and loss
is generated. In addition, when the parameters or the like are
changed according to an operation command in the middle of
performing the test production process, there is a concern that the
production environment will not be maintained when changeover is
performed.
Considering such a situation, an object of the present disclosure
is to provide a production management device of a board production
line that prevents malfunction of a board production device in a
test production process, and appropriately maintains the production
environment.
A production management device that manages board production of a
board production line according to claim 1 includes a board
production device that performs various types of production
processing with respect to the board and an inspection device that
inspects the produced board, the production management device
including: a permission determination section that, before
transition from a test production process, in which the inspection
device inspects a given quantity of initial boards produced by the
board production device, to a later main production process,
determines permission for performing an operation command received
by the board production device, based on an inspection state and an
inspection result of initial boards inspected by the inspection
device and a processing management section that controls processing
of the operation command in the board production device based on a
determination result by the permission determination section.
With this configuration, the permission for performing the
operation command received by the board production device is
determined by the permission determination section. Accordingly,
the processing of the operation command in the board production
device is controlled by the processing management section in the
test production process. Therefore, malfunction of the board
production device is prevented. In addition, processing of an
operation command that changes the parameters or the like in the
board production device is controlled by the processing management
section. Accordingly, the production environment of the board
production line configured by changeover is appropriately
maintained.

DESCRIPTION OF EMBODIMENTS
Hereinafter, an embodiment of a production management device of a
board production line of the present disclosure will be described
with reference to the drawings. The board production line is used
in manufacturing a board product, such as an integrated
circuit.
Embodiment
Overall Configuration of Board Production Line
In the embodiment, board production line 1 is provided with
multiple board production devices 10, multiple inspection devices
20, and board conveyance device 30. Board production devices 10
perform various types of production processing with respect to a
board. Inspection devices 20 inspect boards produced by board
production devices 10. Board conveyance device 30 is configured of
a belt conveyor and the like, and consecutively transports boards
in the conveyance direction (left-right direction in FIG. 1). In
addition, each of the devices 10 and 20 of board production line 1
is connected to be able to communicate with a host computer 40 via
a network.
In the embodiment, board production line 1 is configured to include
screen printer 11, printing inspection device 21, multiple
component mounters 12, optical inspection device 22, reflow machine
13, and functional tester 23, in an order from the furthest
upstream (head) side in the conveyance direction of the board.
Screen printer 11, component mounters 12, and reflow machine 13 are
board production devices 10 of board production line 1. Printing
inspection device 21, optical inspection device 22, and functional
tester 23, are inspection devices 20 of board production line
1.
Screen printer 11 prints solder paste at mounting positions of
electronic components on the loaded board. Note that, in the
embodiment, screen printer 11 is positioned furthest upstream in
board production line 1. Board production line 1 is commanded to
perform various types of production processing with respect to the
hoard after a board is loaded into screen printer 11. Specifically,
when a board is loaded into screen printer 11 by an on-machine
operation or the like of the operator, the printing of the solder
is automatically started with the board as a target.
Printing inspection device 21 inspects the printing state of the
board on which solder has been printed by screen printer 11.
Component mounting machine 12 mounts electronic components on the
solder of the board transported from the screen printer 11 side. In
the embodiment, multiple component mounters 12 are disposed in the
conveyance direction of the board. Optical inspection device 22
inspects the mounting state of electronic components on the board,
such as whether the correct electronic components are mounted on
the board transported from the component mounter 12 side, the
mounting position or the posture of the electronic component, and
the like.
Reflow machine 13 heats the board transported from the component
mounting machine 12 side, melts the solder on the hoard, and
performs soldering. Functional tester 23 performs functional
testing inspection of the soldered board. Specifically, function al
tester 23 gives a predetermined input signal to the board, and
obtains an output signal corresponding thereto. In addition,
functional tester 23 tests whether or not board functionality as an
electronic circuit is normal, based on the obtained output
signal.
In this manner, board production line 1 produces the board product
by transporting the board to board production devices 10 and
inspection devices 20, and performing various types of production
processing and inspection processing. In addition, the
configuration of board production line 1 is appropriately added to
and changed corresponding to the board type to be produced and the
like. For example, there is also a case where board production line
1 is configured to include a board supplying device or a board
flipping device, a shield mounting device, an adhesive application
device, an ultraviolet ray irradiation device and the like, as
another board production device 10.
Host computer 40 monitors an operation situation of board
production line 1, and performs control of each of the devices 10,
20, and 30. Host computer 40 has storage device 41 configured of a
hard disk, a flash memory, or the like. In storage device 41,
various types of data for controlling each of the devices 10, 20,
and 30, are stored. Specifically, storage device 41 stores
production plan data M1 (refer to FIG. 2) including the type and
the quantity of the board to be produced, a control program for
operating each of the devices 10, 20, and 30, and so on.
(Overall Configuration of Production Management Device)
As illustrated in FIG. 1, production management device 50 of board
production line 1 is provided with permission determination section
51 provided in host computer 40, processing management section 52
provided in each board production device 10, and test production
data M2. Permission determination section 51, before transition
from a test production process to a later main production process,
determines the permission for performing an operation command
received by board production device 10, based on the inspection
state and the inspection result of an initial board by inspection
device 20.
Here, board products are produced by board production line 1 by
performing a test production process and a main production process.
The "test production process" is a process of producing a given
quantity of initial boards determined in advance by board
production device 10, and performing specified inspection
processing by the inspection device 20 on the initial boards. The
"main production process" is a process of mass-producing the same
type of board as that of the test production process according to
production plan data M1. Note that, board production line 1 is
configured as a production environment, that corresponds to the
board type to be produced by the necessary changeover being
performed before the test production process. In addition, there
are cases where initial boards are produced as dedicated boards
used only for the inspection, and there are cases where initial
boards are produced as a portion of production boards while also
being used for inspection.
In addition, the content performed for the test production process
is different for each board type produced by board production line
1. In the embodiment, as illustrated in FIG. 2, test production
processing is performed based on test production data M2 with which
the test quantity, the inspection type, and the restriction type in
the test production process are associated for each board type (A,
B, and C of FIG. 2) to be produced by the main production process.
The "test quantity" of test production data M2 is the quantity of
initial boards to be inspected in the test production process, and
corresponds to the "given quantity."
The "inspection type" of test production data M2 is the type that
corresponds to the inspection result that is finally required in
the test production process. In the embodiment, inspection device
20 is any of printing inspection device 21, the optical inspection
device 22, and functional tester 23, as described above.
Accordingly, in test production data M2, the inspection type which
corresponds to any of the inspection devices 20 is set. The test
quantity and the inspection quantity are determined, for example,
according to the production results of the board type or the degree
of change in the production environment due to changeover.
More specifically, in a case where the board to be produced in
board production line 1 is new board type A, functional testing is
set as the inspection type (No 1 of FIG. 2). In addition, in a case
where the same board type A is produced again in the same board
production line 1, considering the production result, and the
degree of change in the production environment due to changeover,
optical inspection is set as the inspection type (No 4 of FIG.
2).
The "restriction type" of test production data M2 indicates the
level of restriction to be performed with respect to the operation
command received by board production device 10. Here, the
"operation command" received by board production device 10 is a
command which requires an operation of board production device 10.
Specifically, included in operation commands are a load instruction
to load a board to board production device 10, a change command to
change a parameter related to production processing, and an
exchange command to exchange an electronic component set in a
component supply device (not illustrated) at component mounting
machine 12. Board production device 10 receives the above-described
operation command after an on-machine operation is performed by the
operator, or after other operation, disposition, or work that leads
to the need for operation of board production device 10.
Specific restriction content in the restriction type of the test
production data M2 varies according to the type of board production
device 10, for example, in type L1, transition to the main
production process, exchange of electronic components, and changing
parameters, and the like are set to be prevented. Permission
determination section 51, before board production line 1
transitions (including the time in the middle of performing the
test production process, and in the middle of being on standby of
the start of the main production process) from the test production
process to the main production process, determines the permission
for performing the operation command received by board production
device 10, based on the restriction type of test production data
M2.
The determination result by permission determination section 51 is
stored as restriction information data M3 in storage device 41 of
host computer 40 (refer to FIG. 1). Processing management section
52 controls processing of the operation command in board production
device 10 based on the determination result by permission
determination section 51. Specifically, in a case where board
production device 10 receives the operation command by on-machine
operation by the operator, processing management section 52
controls whether to perform the processing which corresponds to the
operation command with reference to restriction information data
M3.
For example in a case where the operator performs an incorrect
on-machine operation of starting the main production process in the
middle of performing the test production process, permission
determination section 51 restricts the performance of the
transition processing to the main production process based on
restriction information data M3. Meanwhile, for example, in a case
where an examination operation of board production device 10 or a
confirmation operation of parameters are received in the middle of
performing the test production process, permission determination
section 51 performs these types of processing based on the
restriction information data M3.
Control of Board Production Device by Production Management
Device
The control of board production device 10 by production management
device 50 will be described with reference to FIGS. 2 to 5.
Permission determination section 51 of production management device
50 performs determination processing at a certain time, and
generates or updates the restriction information data M3. The
timing at which the determination processing is performed is before
the transition from the test production process to the main
production process, for example, the time when changeover has been
completed, the time when the inspection result is input from
inspection device 20, the time when the notification is received
from board production device 10, or the time when a certain period
of time has passed from the previous determination processing.
Here, according to production plan data. M1 illustrated in FIG. 2,
a case where board type A is produced (No 1 of FIG. 2) will be
described. As illustrated in FIG. 3, permission determination
section 51 obtains the test quantity, the inspection type, and the
restriction type in the test production process which corresponds
to the main production process to be performed next based on the
production plan data M1 and the test production data M2 (step 11,
[hereinafter, "step" will be written as "S"]). Here, "1" is
obtained as the test quantity, "function inspection" is obtained as
the inspection type, and "L1" is obtained as the restriction
type.
Next, permission determination section 51 obtains the inspection
state and the inspection result in the test production process by
board production line 1 (S12). Specifically, the inspection state
includes whether the initial board is in the middle of production,
the quantity of initial boards which have started to be produced
and the like. In addition, the inspection result includes the
result of the inspection which is finally required, the result of
intermediate inspection before the final inspection and the
like.
Next, permission determination section 51 determines the permission
for performing the operation command received by board production
device 10, based on the obtained inspection state and the
inspection result (S13). Then, permission determination section 51
generates restriction information data M3 based on the result of
the determination (S14). In addition, permission determination
section 51 updates the data in a case where the above-described
restriction information data M3 is already present (S14).
Specifically, permission determination section 51 determines
whether the inspection result obtained by functional tester 23 that
performs the inspection of the inspection type "function
inspection" designated by the test production data M2 (S13) is
accepted. In a case where the test quantity is set to be a plural
number, permission determination section 51 performs acceptance
determination with respect to the test quantity of initial boards.
Based on the determination result and the restriction type "L1,"
permission determination section 51 generates or updates
restriction information data M3 to restrict target operation
commands (S14).
In addition, in a case where board production device receives an
operation command, processing management section 52 of production
management device 50 performs control of the processing of the
operation command. Specifically, as illustrated in FIG. 4,
processing management section 52 determines whether the permission
for performance is necessary by permission determination section 51
with respect to the received operation command (S21). For example,
in a case where the operation command is, for example, adjusting an
illumination lamp or opening and closing a work door, which is not
related to the production of the board, processing management
section 52 determines that permission is not necessary for the
result of the permission determination (S21: No).
Meanwhile, in a case where the received operation command requires
permission for performance according to the restriction type (refer
to FIG. 2) (S21: Yes), processing management section 52 performs
inquiry to host computer 40 (S22). The inquiry includes the content
of the received operation command and information which identifies
the board production device 10 that received the operation command.
Host computer 40 sends out a permission signal or a non-permission
signal to board production device 10 to which the inquiry is
performed based on the content of the operation command, the
restriction information data M3, and the like.
Processing management section 52 determines whether the received
signal is a performance permission or a performance non-permission
(S23). In a case where the result of the permission determination
is not required in the processing of the operation command (S21:
No), and in a case where the permission signal is received from the
host computer 40 (S23: Ye), processing management section 52
performs the processing of the operation command (S24). Meanwhile,
in a case where the non-permission signal is received from host
computer 40 (S23: No), the processing of the operation command is
restricted so as not to be performed.
In addition, host computer 40 that receives the inquiry in S22, as
described above, sends out the permission signal or the
non-permission signal to board production device 10. Specifically,
as illustrated in FIG. 5, host computer 40 determines the content
of the operation command (S31). In addition, host computer 40
refers to the restriction information data M3 which has already
been generated or updated by permission determination section 51 in
S14, and extracts the result about the permission for performing
the processing of the operation command.
In a case where the result of the extracted performance permission
is permission (S32: Yes), host computer 40 determines the presence
or the absence of the restriction by a manager of board production
line 1 (S33). The manager has authority to integrally manage the
production of boards by board production line 1. In a case where,
for example, a stop instruction of production or an instruction of
invalidating the on-machine operation in board production device 10
is received from the manager (S33: No), host computer 40 sends out
the non-permission signal with respect to the processing of the
operation command which was the inquiry to board production device
10, regardless of the result of S32 (S36).
Next, in a case where the restriction is not performed by the
manager (S33: Yes), host computer 40 performs determination (S34)
of the presence or the absence of the restriction by an error
report. Here, the "error report" is received by host computer 40
beforehand regarding various errors detected in each of the devices
10, 20, and 30. In a case where it is determined that interruption
of the performance of the test production process or transition to
the main production process is to be restricted, based on the
content by the abnormality report (S34: No), host computer 40 sends
out the non-permission signal with respect to the processing of the
operation command which was the inquiry to board production device
10, regardless of the result of S33 (S36).
Meanwhile, in a case where the restriction due to the error report
is not performed (S34: Yes), such as a case where the content of
the error report is minor, or a case where the error which was
reported by the manager or a maintenance worker has been cleared,
host computer 40 sends out the permission signal with respect to
the processing of the operation command to board production device
10 of the inquiry (S35). In a case where the restriction due to the
error report is to be performed (S34: No), host computer 40 sends
out the non-permission signal with respect to the processing of the
operation command which is the inquiry to board production device
10 (S36).
Here, as described above, board production line 1 of the embodiment
is considered as being commanded to perform various types of
production processing with respect to the board after the board is
transported into the screen printer 11 positioned furthest upstream
in the conveyance direction of the board. In other words, in board
production line 1, after changeover, when boards are consecutively
loaded into screen printer 11, the transition to the main
production process is achieved. Here, in a case where board
production device 10 receives the operation command of loading the
board into screen printer 11, processing management section 52
controls the performance of the transport processing of the board
by the permission signal or the non-permission signal received from
the host computer 40.
For example, in a case where the loading of the board into screen
printer 11 is for producing the test quantity of initial boards in
the test production process, it is permitted to transport the board
into screen printer 11. Meanwhile, after only the test quantity of
boards have been transported into screen printer 11 in the test
production process, until acceptance determination is performed for
the test quantity of produced boards, it is not permitted to load
the board into screen printer 11 for transitioning to the main
production process. However, in the test production process, for
example, in a case where board production device 10 or the like is
adjusted based on the inspection result, it is permitted to
transport a board into screen printer 11 for additional production
of initial boards.
In this manner, processing management section 52 controls the
transition processing from the test production process to the main
production process by restricting the loading of boards into screen
printer 11. In addition, in a case where a board supplying device
is at the head of board production line 1, processing management
section 52 controls the supply of boards using the board supplying
device.
Effect of Embodiment
Production management device 50 according to the embodiment is a
device which manages the production of boards by board production
line 1. Board production line 1 includes board production devices
10 that perform various types of production, processing with
respect to the board, and inspection devices 20 that inspect
produced boards. Permission determination section 51, before the
transition from the test production process in which inspection
device 20 performs inspection on the given quantity of initial
boards produced by board production device 10 to the later main
production process, determines the permission for performing an
operation command received by board production device 10, based on
the inspection state and the inspection result of the initial
boards by inspection device 20. Processing management section 52
controls processing of the operation command in board production
device 10 based on the determination result by permission
determination section 51.
With this configuration, the permission for performing the
operation command received by board production device 10 is
determined by permission determination section 51. Accordingly, the
processing of the operation command in board production device 10
is controlled by processing management section 52 before the
transition to the main production process. Therefore, malfunction
of board production device 10 is prevented. In addition, the
processing of an operation command that changes the parameters or
the like is controlled by processing management section 52 in board
production device 10. Accordingly, the production environment, of
board production line 1 configured by changeover is appropriately
maintained.
In addition, the functional testing that tests the board
functionality by inspection device 20 (functional tester 23) is
included in the test production process. Permission determination
section 51 determines the permission for performing operation
commands related to the transition processing from the test
production process to the main production process, based on the
result of the functional testing considering the given quantity of
initial boards.
In board production line 1, for example, in a case where a new
board type is produced, there is a case where functional testing is
performed of whether the required board functions appropriately in
a similar state to the product. However, in a case where functional
testing is performed, it takes more time to finish the inspection
compared to other inspection. Therefore, in a case where functional
testing is included in the inspection types of the test production
process, the period from changeover to the start of the main
production process becomes long. Then, chances that board
production device 10 receives an operation command by on-machine
operation by the operator or the like increases. In this state,
maintaining the production environment of board production line 1
reliably prevents malfunction, and thus is particularly
effective.
In addition, processing management section 52 controls the
transition processing from the test production process to the main
production process by restricting the transport of boards into
board production device 10 (screen printer 11) that is positioned
furthest upstream in the conveyance direction of the board in board
production line 1.
Board production line 1 of the embodiment is configured such that
the start of production of board is taken to be after a board is
loaded into screen printer 11 positioned furthest upstream in the
conveyance direction of the board. In board production line 1, as
processing management section 52 controls the processing of the
operation command related to the loading of boards, incorrect
transition to the main production process is prevented.
In addition, production management apparatus 50 is provided with,
for each board type to be produced by the main production process,
test production data M2 which contains the type of the inspection
to be performed in the test production process. Permission
determination section 51 obtains the inspection type in the test
production process which corresponds to the main production process
to be performed next from test production data M2, and determines
the permission for performing the operation command received by
board production device 10, based on the inspection state and the
inspection result of the initial board by inspection device 20 that
performs the inspection of the inspection type.
With this configuration, permission determination section 51
determines the permission which corresponds to the board type in
the production plan with reference to test production data. M2, in
other words, permission determination section 51 automatically
switches whether the determination is performed based on the
inspection result by any inspection device 20 according to the
content of test production data M2. Accordingly, since the test
production process which corresponds to the board type is
performed, the production efficiency is improved in board
production line 1.
Alternative Embodiments
In the embodiment, production management device 50 is configured to
include permission determination section 51 provided in host
computer 40, multiple processing management sections 52 which are
respectively provided in multiple board production devices 10, and
test production data M2 stored in storage device 41. However, if
board production devices 10 and inspection devices 20 are able to
communicate, permission determination section 51, processing
management section 52, and test production data M2 may be provided
in an external device other than board production device 10.
In addition, in the embodiment, restriction information data M3 is
stored together with test production data M2 the storage device 41.
However, restriction information data M3, as an indicator of the
result of the permission determination of the operation command of
board production device 10, may be stored in board production
device 10 with processing management section 52. Accordingly, in a
case where board production device 10 receives an operation
command, processing management section 52 can control the
processing of the operation command with reference to the
restriction information data M3 without communicating with host
computer 40.
In addition, permission determination section 51 performs the
determination processing at a certain timing, and then generates or
updates restriction information data M3. Here, after processing
management section 52 restricts the processing of the operation
command, in a case where the inspection result is updated by
inspection device 20, the permission determination section 51 may
determine the permission for performing the operation command
again. Accordingly, restriction information data M3 is
appropriately updated to the latest information. In addition, in a
case where permission is performed by permission determination
section 51, regarding an operation command restricted in advance,
processing management section 52 may be configured to automatically
release the restriction with respect to the processing of the
operation command.
There are cases where the performance of the operation command
received by board production device 10 is not permitted by
permission determination section 51, and is restricted to
processing management section 52. Accordingly, for example, in a
case where the transition processing to the main production process
is restricted, the standby state of board production device 10 is
maintained. However, according to the content of the operation
command, there is a case where the operation command may be
performed as the detection result is updated. Here, as described
above, a configuration in which the restriction is automatically
released based on the result of the permission determination
updated by permission determination section 51 is achieved.
Accordingly, the processing of the restricted operation command is
performed at appropriate timing. Accordingly, for example, in a
case where the standby state of board production device 10 is
maintained, restriction information data M3 is updated by
determining the acceptance of the test quantity by inspection
device 20. In addition, when the restriction of the transition
processing to the main production process is released, board
production line 1 automatically transitions to the main production
process. Accordingly, the standby time of board production device
10 is reduced, and the production efficiency of board production
line 1 is improved.
In addition, in the embodiment, permission determination section 51
determines the permission for performing the operation command in
advance (S13), regardless of the timing when board production
device 10 receives the operation command. However, when board
production device 10 receives any operation command, permission
determination section 51 may determine the permission for
performing the operation command based on production plan data M1
and test production data M2 as necessary. In addition, processing
management section 52 controls the processing of the operation
command based on the determination result of the permission for
performing each operation command. With this configuration,
production management device 50 may not be provided with
restriction information data M3.
